A rare species of bird
A rare species of bird has been re-introduced to a national forest, and researchers have been modeling their population growth over a span of 10 years. In the equation below, the variable “Years Elapsed” represents the number of years since the birds have been re-introduced to this forest. The analysts did not include the value 0 in the model, so the values for years elapsed range from 1 to 10.
(Birds) = 218.86 + 35*In(Years Elapsed)
On average, every three years the bird population increased by

A rare species of owl has been re-introduced to a national forest, and researchers have been modeling their population growth over a span of 10 years. In the equation below, the variable “Years Elapsed” represents the number of years since the owls have been re-introduced to this forest. The values for “Years Elapsed” will take the values 0 to 10. (Owls) = 10 + 1.6*(Years Elapsed) On average, every three years the owl population increased by about Need to know...

Wolves have been re-introduced to a national forest, and researchers have been modeling their population growth over a span of 10 years. In the equation below, the variable “Years Elapsed”, which is acting as the exponent of the value 1.08, represents the number of years since the wolves have been re-introduced to this forest, and will take the values 0 to 10.

I. An island has three species of bird. Species 1 accounts for 45% of the birds, of which 10% have been tagged. Species 2 accounts for 38% of the birds, of which 15% have been tagged. Species 3 accounts for 17% of the birds, of which 50% have been tagged. If a non-tagged bird is observed, what is the probability that it is of species 2? Round to 3 decimal places.

Write a program to help answer questions like the following: Suppose the species Klingon ox has a population of 100 and a growth rate of 15 percent, and the species elephant has a population of 10 and a growth rate of 35 percent. How many years will it take for the elephant population to exceed the Klingon ox population? You can assume that this will happen within 10 years. Use the version of the class Species from Sakai’s Week 7...

5. Feral pigeons (Columba livia domestica) have long been considered the most frustrating pest bird. Flocks of these pigeons pose a threat to crops, livestock, and human health as their large numbers can decimate crops and act as disease vectors for pathogens that affect both livestock and humans. However, in places like New York's Washington Square Park, pigeons are well-loved and well-fed members of the...

introduced Prey Species! Cane toads (Bufo marinus) were introduced to Australia in 1935 in a failed attempt to control an insect pest. Since then, the toads have spread across northeastern Australia, with a population of over 200 million today. Cane toads have glands that produce a toxin that is poisonous to snakes and other potential predators. In this exercise, you will graph and inter- pret data from a two-part experiment conducted to determine whether native Australian predators have developed resistance...
